A solution of 2-(5-phenyl-1-tetrazolyl)thiomethyl-4-ethylsaccharin (Example 30AE, 0.020 g) and 1-phenyltetrazol-5-thiol sodium salt (0.0026 g) in dimethylformamide (1 mL) was heated at 100° C. for three days, then poured into water. Recrystallization of the resulting solid from ethanol-water afforded 2-(4-phenyl-5-thioxo-1-tetrazolyl)methyl-4-ethylsaccharin, 0.012 g, 60% yield, mp 127°-129° C.
